Blackstone Halves Stake in TRW

T. Rowe Price now stands as the largest holder in the vehicle-parts firm.

Insiders at vehicle-parts supplier TRW Automotive Holdings put the brakes on more than 10 million shares, selling them for $591,236,400, an average of $59.10 each, on Feb. 20 and 21.

The selling, which came as TRW (TRW) shares veered away from a 52-week intraday high, was a secondary offering of shares held by Blackstone Group's (BX) Automotive Investors L.L.C. affiliate and certain members of TRW management.
